Sometimes you may need to carry something that there is not a specific rack for. Things like lumber, duffel bags, luggage, or tents and sleeping bags can all be carried outside the vehicle to free up interior space. Roof mounted hard shell cargo boxes and open top baskets will mount to your vehicle’s crossbar system and typically come with universal mounting hardware to fit most crossbar styles. Soft-sided fully enclosed bags frequently come with universal straps to allow you to carry gear on your roof without even requiring a base rack system. If you don’t want to carry gear up high, there are trailer and hitch mounted options as well.
